Patent GB-2036329-A (GB)
Title: Method and device for measuring or detecting a mechanical change of state or its time derivative
IPC: E01F9/669
Filed: 1978-11-23
Abstract: A method is described for measuring a change in the mechanical state aiming at detecting the disturbance the change in state has on a magnetic flux (o). This flux is brought to flow through at least a part of the body (1) under the influence of a driving magnetizing force (H<u0>u). In order to achieve an unambiguous measuring result the average length (//c) of the magnetic circuit is kept constant and independent of the change in the mechanical state. The flux (o) consists partly of a main flux (o<u0>u) having a definite direction and being of such a magnitude that the magnetic properties of the body depart from the region of irreversibility and partly of an alternating, gradually vanishing flux (o<uy>u) superimposed upon the main flux. The alternating flux must have such an initial magnitude that saturation is obtained in both directions of the alternating flux (o<uv>u). After the vanishing of the alternating flux (o<uv>u the disturbance generated through the change in the mechanical state is indicated or registered as a voltage which is induced by the change in flux corresponding to the disturbance. A device which works as explained above comprises means for generating the flux (o) through the body (1) which is arranged to form a magnetic circuit with at least a part of the body (1). This circuit should be essentially free from air gaps and have an average length (//c) for the driving magnetic force (H<u0>u) which is independent of the change in the mechanical state. The device is arranged to force partly the main flux (o<u0>u) and partly the superimposed alternating flux (o<uv>u) through the magnetic circuit. By means of a coil system (5) connected to a measuring or indicating device (8) the change in flux corresponding to the disturbance caused by the change in state is detected.

Patent GB-2029670-A (GB)
Title: Automatic telecommunication switching system
IPC: H04M3/36
Filed: 1979-08-21
Abstract: In a telecommunication exchange it is desirable to be able to detect circuits, which operate erroneously, and so are often seized and shortly thereafter released because they cannot operate correctly. For each group of like circuits, e.g. outgoing junctors, there is a first register to register the total number of times the circuits of the group have been seized. A second register is individually allocated to each circuit of the group to register the first seizure plus a successful operation thereof. A third register is allocated to the group to store a reference value which is equal to the number of seizures that should be registered in a first register in order that with a high degree of probability each of the circuits of the group should have been involved in at least one successful operation. When the contents of a first register are at least equal to those of the third register, the various corresponding second registers are analysed to find the faulty circuits.

Patent GB-2052064-A (GB)
Title: Portable strip chart recorder
IPC: G01D9/00
Filed: 1979-12-19
Abstract: Strip chart recorders of known types for recording of findings of measured quantities as curves or traces on a paper have hitherto been bulky and heavy devices (approx. 10 kg) and therefore been non-portable and difficult impossible to hold in hand during the recording session. The strip chart recorder disclosed herein which weighs 1 kg has successfully been diminished relative to known types without diminishing the width of the recording area simultaneously. This result is achieved by (cf. Figure 1) letting the pen arm (8) of the pen motor (3) occupy almost the entire length of the apparatus, by placing it in the cover (1) and by placing the store of the strip chart (9) beneath or below the pen arm (8).

Patent GB-2074768-A (GB)
Title: Track circuit
IPC: B61L23/04
Filed: 1981-04-08
Abstract: A broken rail detection circuit for use with an A.C. track circuit in a 'double rail return' traction system. A track circuit receiver is driven by the signal across an impedance bond and operates a relay to disconnect the signal so causing the relay to cycle. In series with the receiver input is a signal from the centre tap of the impedance bond, which is normally at earth potential and does not affect the relay cycling. In the event of a rail break a significant output is obtained from the centre tap, which either cancels or replaces the original receiver input signal with a continuous signal. The relay therefore ceases to cycle in either event and thus provides a break indication. <IMAGE>
